Abstract
A Push-To (PT) service of Session Initiation Protocol (SIP) based session services, and particularly, the method and system that even if a target PT client terminal is in the unregistered state to the SIP/IP core and a PT server has not received ‘PT service setting’ from the target PT client terminal yet, a particular PT client can use the PT box of the target PT client terminal.
Claims31
A method of handling a Push-To (PT) session service in a wireless communication system supporting a session initiation protocol (SIP), the method comprising:
- receiving, from a terminal, a SIP invite message to initiate a session for at least one of many target terminals;
- checking whether a PT service setting has been received from each of the target terminals;
- checking PT box access condition information associated with one or more particular target terminals, if the PT service setting has not been received from those one or more particular target terminals;
- and
- determining whether to forward the SIP invite message to the PT box or to transmit a failure message to the terminal based on the checking of the PT box access condition information.
A method of handling a Push-To (PT) session service in a wireless communication system supporting a session initiation protocol (SIP), the method comprising:
- transmitting a session invite message to one or more target terminals;
- and
- receiving a session invite response message from a PT box when PT box access condition information, which is associated with one or more unregistered target terminals, is set to unconditional PT box routing.
A method of handling a Push-To (PT) session service in a wireless communication system supporting a session initiation protocol (SIP), the method comprising:
- transmitting a SIP PUBLISH message to a PT box via a PT server;
- receiving, from the PT box, a SIP message that includes particular information;
- and
- transmitting, to the PT box, a SIP invite message using the particular information in order to check certain data stored in the PT box.
A method of handling a Push-To (PT) session service in a wireless communication system supporting a session initiation protocol (SIP), the method comprising:
- receiving a SIP invite message to initiate a session for at least one of many target terminals;
- checking each PT service setting for each of the target terminals respectively;
- transmitting the SIP invite message to the PT box if the PT service setting has not been received from one or more particular target terminals;
- receiving a SIP invite response message from the PT box, wherein the SIP invite response message includes PT box access condition information of the one or more particular target terminals.
A method of handling a Push-To (PT) session service in a wireless communication system supporting a session initiation protocol (SIP), the method comprising:
- receiving a request from a client in order to initiate a session for at least one of many target clients;
- checking storage entity access information for one or more unregistered target clients or at least one of unavailable target terminals;
- and
- determining whether to send the request to a storage entity or to send a failure message to the client according to the checking step.
